  Mine did this a few months ago :(
For me.....
No other signs other than...
a)Clutch wouldn't/didn't release (couldn't understand why it wouldn't go 
in gear anymore) ... there was to much movement forward from the main 
crank in the block when the clutch thrust bearing tries to push the 
clutch cover plate to release the clutch plate.
b)Metal filings in the engine oil and with a magnetic sump plug the one 
of the thrust bearings came out on the end of the magnet when I took the 
plug out!
To check
1) Check end play on crank drive pulley ie doesn't have excessive play 
and is in tolerance.
2) Drop the sump and take off rear end cap, check thrust washers are in 
place - recheck tolerances and replace with new ones to compensate for 
mileage.
To Repair
1) Replace thrust washers with new ones correct new ones in tolerances 
(to compensate for mileage). Parts $10
2) Obtain replacement engine New or Refurbished $600 - $5000 +
3) Repairable block/crank - Brake down engine and re machine replace 
necessary parts $1000 +
4) Repair engine with replacement machined block and crank plus parts as 
necessary $2000 +
Notes:
Make sure the thrust washers are in the right way round!
The grinding of gray cast iron block on a //Tuftrided high carbon steel 
crank - is a very quiet sound... but an expensive one!
